February 19, 1473 –
Nicolaus Copernicus (or Mikolaj Kopernik or Nicolaus Koppernigk – apparently he was running some sort of ponzi scheme at an early age and was giving different names to different people) was born in Poland on this date.
He stated an early theory that the Earth and the planets move around the Sun that led the way to our understanding of planetary movement.
